SACCHAROMYCES/ZINC/IRON/GERMANIUM/COPPER/MAGNESIUM/SILICON FERMENT.

Valuable CAS - / ASTRINGENT

This unique fermented mineral complex combines five essential minerals—zinc, iron, silicon, copper, and magnesium—with Saccharomyces cerevisiae yeast. The fermentation process transforms these minerals into highly bioavailable forms, allowing for superior skin recognition and absorption to deliver enhanced dermal benefits.

Science

This ingredient functions by significantly enhancing the bioavailability of its mineral components through Saccharomyces cerevisiae fermentation, making them readily recognized and utilized by skin cells. These bio-active minerals act as crucial co-factors in numerous enzymatic reactions vital for skin health, including protein synthesis and cellular metabolism. Specifically, copper facilitates collagen production and skin repair, while zinc reduces inflammation, supports healing processes, and promotes collagen synthesis through optimized cell division. Magnesium energizes skin cells, fortifies the skin's natural barrier, and ensures hydration. Iron aids in protein formation, boosts cell growth, and improves immune functions. Silicon is essential for the normal development of bone and connective tissue, strengthening the skin's protein matrix. Collectively, these fermented minerals deliver essential nutrients, provide antioxidant protection, reduce inflammation, boost collagen synthesis, improve skin elasticity and texture, reinforce barrier function, moisturize, soothe irritation, and contribute to a more even skin tone.

Stability

The ingredient maintains stability for up to one year under ordinary conditions. For optimal shelf life, storage at 23-25°C is recommended, though it can be stored between 16°C and 32°C if precise temperature control is unavailable. Freezing should be strictly avoided.


Safety

CIR Status
Safe as used
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) generally considers 'Yeast-Derived Ingredients' (a broader category including Saccharomyces ferment) safe for use in cosmetics. However, EWG Skin Deep classifies 'Saccharomyces/Zinc/Iron/Germanium/Copper/Magnesium/Silicon Ferment' as 'Restricted' for EWG VERIFIED products, indicating a need for more substantial safety data for their specific certification process. No particular fire, explosion, or other mechanical/hydroscopic hazards have been identified.
